Vibrations are supposed to stop them, although I've never tested it. That's one pest we don't have in Ireland, them and snakes.I seem to remember things like child's windmills stuck in the ground, or anything that makes a noise. Also prickly holly leaves placed in their runs tend to make them think again. Anything like that as there are loads of other places it could go if it gets too inhospitable on your plot.Just don't let on to your neighbours how to send them back.
